View Full Version : PolarYJ: NextGen
it's finally here!!! the moment i get to stop setting up the house/shop and get back to wrenching for the fun of it!!!
So the YJ is going under the knife again, but this time not just a restoration, i'm making changes. i built this configuration with the d44/12bolt back in about 2005. i put these specific IROK tires on it in Jan 2007. things have gone well! but 13yo tires are like driving on grease in the rocks, the 12b is machining it's own ring gear away, and the d44 is cracked and bent and bandaid'd in multiple places. no more spares or hold-overs, it's time for new.
Enter ... the 40s. i got a pretty solid deal on 6 40s that i couldn't pass up. not sure why i need/want 6, but that's what there was. no way i'm putting 40s on 1/2ton axles, so it's time for beef. rear axle is getting an exact duplicate of the full-float 9" in the TJ. same width, same components, just leaves vs links. simplify spare parts and the axle really does work well. front is just getting a GM Dana60, cuz the front is already a GM d44 and this should basically bolt-in. 5.38s, Yukon Competition Zip locker f/r (air operated normally spooled) rear is also getting another 2" of stretch via offset axle perches, and the front might get an inch somehow.

last night i got the 12b out, shockingly everything came loose easy and it fell right out. the only surprise was that the slip in my rear drive shaft was bound up SOLID. glad that didn't break my t-case.

How is the tub doing these days?
Glad you came to your senses and are bolting in a GM D60 :lol:
hey, these axles were awesome for a LONG time ... all things considered, i'd not change the past.
a few years ago i did that "frame off" resto and fixed a LOT of the rust in the tub. not saying it's perfect or super pretty, but still more solid than i need to beat off rocks :thumbsup:

No, I meant vs. building a custom 60-9 for the front. Swapping a GM D60 makes way more sense IMO. I agree that the outgoing setup treated you pretty well.
Forgot about that other work you've done on the tub :thumbsup:

so the YJ has to be trail ready for a run April 17th ... after that the '55 gets pulled back out for a summer project.
got the axle flanges and spring perches all set up last night and half burned in. tonight i hope to finish welding those and bend/weld on a matching tube truss to the TJ.
still missing shock mounts and the traction bar mount, but will probably install those with the axle bolted into it's final place. need weight on it for the traction bar and to flex it for the shocks.
also, these ruffstuff 2+ perches are awesome.

I used their 1" offset mounts (really just perches with 3 holes drilled in them) for the j10.
i re-drilled an extra hole 1" offset into the 12bolt perches, so i only gained 2" from these. but should be just enough to keep the 40s off the body behind the door.

Cutting will be required :lol:
i got the flanges and perches fully welded last night, then built and 50% welded the truss. it's the same link mount truss i put on the TJ since i had a spare plate already cut and the tube lying around. pretty sure it wasn't needed, and pretty sure it isn't adding a whole lot of extra structure, but the plate actually ended up basically dead level with the spring perches!

Yeah, I'd go w/ it's actually worse than an angry grill myself :yuk:
Honestly, had to rib a bit...I had a YJ, loved it!!! While the square lights veered from the original look of the SWB, I still wholeheartedly believe that the grille should simply not be messed with...factory all the way. Be it any model out there, it stays ;)
what ya think B, 40s on the 55?
it happened, i got em on there this weekend. the stupid Chineseium wheel bearings didn't fit, and no one local had any better, so i ended up scavenging the Timken's from the front 60 :lol:
love the new departure angle, not super excited to go to a mini-comp-cut to make them fit. but i'll make ti look good i hope. with the tire and slightly taller spring perches, the frame gained 4 full inches of clearance. now i have 13.5" under the diff, 24.5" at the skid, and 28" at the frame. i kind of wish it was a little shorter maybe.
left it all stripped n ready for the front 60, just need to sort a few things out first. drill n re-tap the spring plate stud holes, new center pins in the springs, and both fixed spring hangers have rips in them. so getting new HD hangers, mounting them 1" fwd, and re-drilling the center pin holes on the axle 1" off. the shackles were quite vertical, so they shouldn't even notice extra inch.

seriously though, this summer will probably be local shake-downs and re-learning, along with rebuilding the savings. but i REALLY want to get out and do some new stuff bad. i REALLY want to get out west. moab would be like $1500 in fuel, maybe i can find a passenger who would like to split some of that.
:chug:
so tonight i'm going to run go carts with guys from work, and tomorrow i need to spend with the wife cuz i'm out of town wed/thrus nights, before a buddy shows up friday night from out of town. so nothing more is going to happen til next week.
i did order what i think is everything i need to get the d60 bolted in 2" fwd of before. bolts, taps, mounts, etc, so next weekend will hopefully see some good progress.

:rock: looks good man.
Are you going to run a axle wrap bar? Curious if mounting the axle center line that far back on the springs will make it wrap
so the reviews i saw on these perches all claimed less wrap with them. basically making the lever arm of the perch longer to resist it. on that note however, i will without question be running an anti-wrap bar! had one before, (you can actually see it hanging under the jeep) it really makes a difference when bound up or climbing.
i'm going to re-make the bar though. i bought new axles mounts that have more separation to hopefully lower the forces in the bushings a bit, along with the 2" stretch. i'll at least re-use all the old bushings and just re-tube it, it's already been cut and spliced 2 other times.

She's looking really good
well, made a little progress over the weekend once i got back from the work trip. i need my high steer arms to show up, and i need to clean up the 60 really good with the new kingpin hardware / paint.
so the axle basically bolted in where the GM d44 had been, but it wasn't that easy. first thing was to drill/tap the spring plate housing bolt holes for 3/4-16 to more easily make studs and to be stronger, then i didn't realize that side spring plate wasn't symmetrical and fought that for a while. next, both of my spring hangers were starting to rip, along with wanting to push them fwd, so they got replaced and moved 1.5" fwd. the longer shackles are still 45deg or less at max angle without moving the shackle pivot. also re-drilled the center pin hole in the spring perches by 1", for a total of 2.5" front stretch over both stock and what i was running prior. now 5.5" over stock for a nice 99" wheelbase.

Do you think you'll need to relocate your steering box with the front stretch?
Do you think you'll need to relocate your steering box with the front stretch?
undecided so far ... still waiting on parts to come in for the test fit. i ordered these high steer arms. my current plan-A would be a tie rod or double-ended ram that runs JUST under the leafs, mid connector bolt. the drag link could then run to the top of the arm over the leaf. let them live over top of each other but separated enough to never contact.

ULTIMATE goal ... is the 4500 style steering. servo to the double ended ram with a manual steering box and drink link still connected in.
xj_man_646
03-04-2020, 02:42 PM
Do you want to maintain a mechanical connection just for the bling factor, or are there rules at play for whatever comps you plan to join? If you're already debating a double ended ram, I'd just go full hydro and never worry again.
i'm really not sure on the steering rules for RC Rocks ... i should look into that.
the double ended ram makes all the sense in the world for power of steering, it's time, i need that. but having driven a full hydro rig back to camp while being towed, it SUUUUUXXXX. to that end, everyone i've talked to who has run the 4500 style has said the same thing. it has the steering feel and feed back of mechanical steering while racing, but the power of full hydro in the rocks. that just sounds pretty awesome.
also one more thing a cop couldn't hit me with if i drive this to work at some point. i do have a plate :lol:
xj_man_646
03-05-2020, 10:11 AM
:dunno:. Correct me if I am wrong, but the majority of 4400 rigs run full hydro, so there has to be a reason they don't bother with the mechanical linkage in the fastest class. Not that I think you should change your plans...do what you want :lol:.
Street driving makes some sense. I did see a full hydro steering 1 ton JK on 42's at the Tilted Kilt when I lived in MI, but I'm pretty sure he is generally OK because most of the cops around the Detroit metro have bigger fish to fry than the steering setup on a Jeep :lol:

yeah, the complete lack of any fawks given in MI i miss ... "oh it has a plate? keep driving" ... "oh, you have a title from something you bought? good enough"
i think the biggest thing is with a 4-link double-triangulated front suspension vs the steering. the 4-link travels vertical, where the drag link would want to push with compression like a panhard bar. a nice full travel hit would swing the steering a bit with the 4500 style steering. i'm on leafs and a little bump steer doesn't matter to me ... 110mph across the lake bed, i'd care.
xj_man_646
03-05-2020, 02:46 PM
I think it was Kurt on here who ran mechanical steering with a front 4 link and had no bumpsteer. Pretty sure that was the setup on his TJ.
I guess your logic could make sense though. Didn't think of that aspect.
The other part of full hydro that is attractive to me is no restrictions regarding the steering box or fighting between panhard and draglink lengths / angles (not that it is overly difficult to overcome, but things can get interesting once you start stretching wheelbase more than a couple inches)
if you don't have crazy travel, and set the draglink set up JUST below flat at ride height, there's no reason it should be noticeable on the street. theoretically leaves without a panhard bar should act the same, or worse since the axle can move side to side some.
i feel like it's one of those "in good practice" kind of ideas that is only really an issue at the extremes. like when using 18" of axle vertical travel at 100mph. my 45mph, 10" of travel jeep probably couldn't care less.
smashed out some fab stuff Friday, then cleaning and painting when i had a change to get out there the rest of the weekend. getting close enough i can taste it ... just need my axle guts order to show up.

I'm always impressed with your pace of projects. When you get time you knock a bunch of stuff out :rock:
I vote 4500 steering, because I want to see how it works. Also I think you are right on in your thinking in your comment with bump steer. 2-5" of road travel no big deal. 100 mph suspension travelling 18" big deal.
It's been a long time since i have driven something with full hydro but i didn't mind it at all. The only time it really sucked was when the engine died and you have to steer that bitch out of a trail. End up with popeye forearms.
Thanks! it feels so good to be back at it. my hands are cut up, i have metal splinters, grease i can't wash off that soaked into dry skin, etc. plus the fact that i feel more limber, and my endurance is coming back up off of none to a bit.
right now real steering is on hold, i need to get all the axle guts ordered and see what cash i don't have left.

Bitchin...man, I wish I took that same initiative. Since driving back from CO a few years ago, on a trailer no less, and a bunch of road spray nailed all my undercarriage and turned to instant rust.
It literally went from a brand new vehicle to look like a winter driven rust ride instantly...and it had NEVER been on a winter road :squint:
I'd love to tear it down, respray, etc...but I'm just too damn lazy, and don't have the space I'd like to do it in.
Really appreciate seeing other's work tho, damn that stuff is nice!

you don't need to tear anything apart, you just need a wire brush, an air hose, and ChassisSaver!! (then a top coat of rustoleum cuz it's not UV stable)

can and have, even bought the pinion depth gauges and such ... but excuses and complaining.
local shop is $300, should i just do it myself? i have the stock bearings to make set-up bearings from still. 9" are so much less fuss, and i did still have EMS Offroad, who i bought all the axle guts from, build the 3rd and ship it. but he was cheaper
didn't do a whole lot over the weekend, but did get some detail things together
-new master cylinder
-changed engine oil
-fill the ax-15 (was like a qt low :james:)
-d300 is still over-full n clean, so let it leak!
-cleaned up both frozen drive shaft slip yokes, for the shake down i'll just splice in tube to make them longer. also pulled the 1310 shaft off the shelf from the TJ before i went 1350, it's like brand new. it's maybe 1" to long, so i'll keep the smaller old shaft for a spare.
-front 40s are mounted on the wheels
-installed the traction bar
-installed UTV rear view mirror that clamps to the cage
and cleaned the shop, that always feels good.
the mirror should be good

D60 dropped off this morning with the new guts to be installed! hoping to get it by end of day Friday, but he couldn't promise that.
well ... "early next week" turned into same day!
picked up the axle this morning at 7am when i dropped the wife off for work. with truck down, and the summer only tires on the vette low, she didn't want to drive it in this all-day monsoon. i didn't figure i was going to have an easy time getting the d60 into the back of the TJ.

Sick dude! I need to get back into another crawler.
i need the rear axle parts to show up ...
-rear 3rd member so i can modify the drive shaft.
-rear axle shafts in with the 3rd so i can run the axle and "turn" the brake rotors down with a grinder. dodge d60 rotors are the same as a 3/4ton chevy, except larger dia. i'll grind these for a trail rig vs buying new.
-brake turned down so i can install the calipers, so that i can bleed the brakes.
i'm also waiting to know the rear DS length before i make the front. i'm hoping i can split the difference and still use the same shaft front and rear.
before all that,i still have stuff to do:
-finish welding and install the steering
-run air lines and switches
and other crap ...
small rant ... why on earth does ARB, and now Yukon (i assume to follow ARB) use 5mm air line for lockers!?!?! you can't get a damn 5mm PTC fitting with an NPT thread, only BSPT. is this really just to make you buy their entire system "cuz it's easier"? it's stupid. not to mention they have you tap the housing for 1/4" NPT for the bulkhead fitting. is that fitting really a custom pc and NPT on one side and BSPT on the other, or are they asking us to just ram the fitting home. ugh.
on that note however, 5mm line, if properly cut/prepped, will go into and seal really nicely to a 3/16 PTC connector. it's just hard to get the line out later.
still moving fwd, still waiting on rear axle guts. front brakes are connected in. steering is welded and painted, just waiting on install tonight. air switches are mounted and plumbed with the exhaust just an 18" run under the seat to keep mud out. front axle is fully assembled, locker function from switch confirmed, just needs fluid now that the RTV is cured.
i really need a 90* fitting at the axle though, will order that with all the trail spare/repair parts.
i really like these mechanical shuttle valves so far, keeps the system super simple.

My only experience with arb lockers wasnt the best. My moms TJ and my old TJ both had them in the rear dana 44s and they were always leaking. :dunno:
I take it you didnt have to mess with the steering to much with pushing the front axle foward?
so the steering is together as of moments ago ... but not the final solution. i'm convinced that i'll go to the 4500 style steering before too long. so, with that in mind, i set up the drag link for 3 turns lock-to-lock on the stock d60 steering stops. i'll open that up some once i have the ram and chromoly shafts, so a little room left to go further later.
drag link should be high enough that the lower tie rod never gets into it, even without bump stops. but now i have to worry about the lower rod, and later the lower ram. it's at least above the axle CL. i also like how flat the drag link came out, should be nice on street if i ever drive it. i also feel like a later project would be to weld a double shear plate to the pitman, easy enough i think. could build a double shear set up onto the high steer arm too really, and might weld a nut to the knuckle for the 5 bolt hole. little stuff that's getting skipped til i NEED it, or need a project.

ARB answer, yes...they do that so you buy their overpriced BS! Found out several years ago the hard way...back when I had my black TJ, super pissed about that. I ended up buying spares that I still have in a bag somewhere in my garage heep today :lol:
Those switches are nice...use them on my JK, they were installed by the PO and I like them. I use CO2 for my lockers, a small Powertank setup, super slick.
I need a new heim up front eventually...still ok to drive, but there is just a slight bit of wear and movement that I'll need to address before too long.

Yes sir! 1-1/4" solid, ground/hardened/polished steel rod with the sleeve pucks for the carrier and axle ends. i have pucks for d44, d60, and all 3 9" carrier bearing sizes. i also have 2 different semi-float bearing end cup dia, a d60/14b threaded puck for spindles, and a buddy just made a d44 threaded spindle puck so we can build his 944.
willing to rent it to ya for shipping if needed. would be one box of adapters and one tube of the rod. i cleaned up and painted an empty stock 9" case to use with the fixture on this axle, it's nice to be able to reach in thru the pinion support. he might have bought it though for the 944.

i "designed" all the parts based on what was out there. a local machine shop did the round pucks for me way back cheaper than i could buy them online. a dude at SB&D machine shop turned the threaded pucks as a "g-job" for me.

shoot, that aint bad.
one thing Eric talked about was using a D50 spindle and hub since you could get them for dirt cheap. but i don't know what that means for brakes.
i used the TMR 3/4ton caliper bracket for GM d60. however, the dodge hubs i used have a different rotor offset vs the spindle flange. i accounted for this by actually mounting the TMR bracket to the back side of the spindle flange. had to cut the bracket to fit over the axle tube and only used 4 bolts then. it's about 1/16" off from perfect, but the caliper slides don't care. on the TJ i did make a spacer, but not on the YJ. you'd have to figure the difference for the different flange thickness if doing similar to me.

few small updates ... really been working on my tractor, the yard, and my GMC. so got the rear fenders cut and i'm pretty happy with em. not a full comp-cut, still lots of clearance, but has that full-boddied look. i've had issues with the inner axle seals on the TJ, so decided i would pre-stretch them for easier install. can't hurt right? 1.5" shafts, so 1.5" tube that i polished up a bit. the new rear 3rd showed up with the ZIP locker and 5.40s, just need to drill in the air line bulkhead and bolt this thing in!
-assemble rear axle
-drive shafts
-"turn" brakes
-bleed brakes
-DRIVE IT ... and flex it to measure
-new shock mounts / order shocks
-*hopefully not* all new bump stops since i've never run any
-then drive around in the yard cuz the wheelin trip got canceled :cry:

this air line routing feels stupid, but is what the directions, and Eric said to do. also managed to get this bulkhead fitting in without stripping it this time, haha.
then the MOSER shafts came in and one was long, good thing they had extra splines cuz my custom length shafts had to be cut down by .75". got a nice little slug for my desk at work now.
cut up the old rear drive shaft and added an inch for the new front. sleeved inside with the plug welds. she'll last more than long enough to work out all the details to order good new shafts. for a 2pc drive shaft and a stock axle pinion support, that's not a bad angle.
then, du da DA! she lives!!! still needs shock mounts to be trail ready, and eventually a real air system. of course i still have a full list of future plans :pimp:

brakes are a little spongy, but the front calipers are so much bigger it can't be unexpected.
gears vs tires feels pretty good, but i guess we won't know til i'm on the trail.
steering is week for sure, but is what it is. it's quicker than before, and turning more crap this time. feels fine while driving it, but 4x4 with both lockers in that **** feels like manual steering.

home from NC ... but going back next week. i had to miss the wheelin trip i had planned, and kinda dragged this wrap-up out a little bit.
dug into shocks finally. figured out all the new mounts n lengths, going to use the same Bilstien 5125's front and rear. also sticking with the 90s Ford f350 upper mounts, but cutting them down a bunch. rear will get out-boarded and half frenched into the frame now. steering needs a little frame notch, after wiggling the jeep around it settled down and touched. i'll also cut the misalignment spacers down by 1/4" without effecting their travel.
while looking at it all and only doing this once as a final solution, i decided to cut off the rear frame spring hangers like i did the front for HD hangers. will also be moving them back another 1" for a new total rear stretch of 4". the rear DS i have in it is on the long side, so no need to even change it.

Looking good!
Any plans for the steering arms? While Chevy knuckles are a bit stronger than the Ford ones on my Jeep, the studs are also a weak point, especially when you add hydraulic steering. The keyed knuckles and hi-steer arms seem to be the best solution.
Also, I love that rear 9" build with the 8-lug, full float outers. Makes me want one.

Thanks! fawk i'm excited to go play!
right now i'm not doing anything special with the arms. they are non-keyed basic arms, springless, but they are drilled for the 5th bolt. with the 3/4" tie bolt going to the factory steer arm, and the tie rod being way closer to the factory arm than the high steer, i'm much less concerned. my only thought right now has been to run a nut/bolt into the 5th hole and then weld the nut hard solid to the knuckle.
i really love this rear axle design, it's why i duplicated it to the YJ from the TJ. my only complaints are around the seals. the inner seals actually took me a pretty good learning curve, think i have em now. the pre-lube and assembly order are KEY. also the main spindle seal on the hub isn't made to be an oil bath, just grease. so when the inners leak ... the outer will.

so i got WAY wrapped up in work recently, and that's where i usually post updates :lol:
the shocks all on, same shocks f/r to make things easy. though, with them outboard in the back it is a bit over-damped back there. not that i drive it over 5mph much, but some more weight would help this and balance things out. for more protection i already have some corner guards that i've never put on, as well as i'm getting a free fold-down Poison Spyder tire carrier to put on it. better protection, balance, looks good, etc.
i used the f-350 towers and cut them up as needed. back was frenched in 1" to help tire clearance.

I had suck downs front and rear on the old tj (front was just the big winch) I'm not sure if I ever did anything hardcore enough to need them but I liked to think they help. The front of that tj had a ton of droop.

the YJ never had crazy droop, but it never climbed well at all. was being followed by some old-school guys on one trip and after watching me for a bit they suggested one. the leaves would unload quick and provide very little control of the front axle. this should not only help my CG a little to get more weight on the front for traction, but also keep the front axle from dancing and bouncing off traction.
here's hoping.

What am I looking at :dunno:
Is that the rad outlet up against a crossmember?
lower rad outlet, and the new suck-down cross member.
i thought for sure i would only be really close to the rad outlet, but still over top of it. oops.
looks like i can actually lower the rad by most of that without doing anything but re-drilling the mounting holes in the rad flange. after that maybe a small clearance in the cross member web will do it.

Just put a 4" tube through the cross member and run the hose through it :lol:

i do have some spare 3" 3/8-wall DOM chunks left from cutting the Spider-9 to width :roflmao:
So I moved the radiator down 1.5", didn't even need to clearance or move anything else. Just re-drilled the mounting holes. Also made a small clearance in the crossmember web, game on.
Then I got a new electric fan in and did the first real test fit in the enclosed. It's TIGHT. Backed in since that axle fit between the wheel arches, was a huge pain in the ass. Looks like I need the rollers to make things easy.

I am way too lazy to have to swap tires on and off everytime I tow my jeep.

Yeah, will see how this goes. Camping in the trailer and the extra space might be even better. Floor jack, 20v 1/2" impact, and the swap only takes like 3min.
the new stuff is working awesome, just new tires alone has been huge. this first picture is actually with the 37s off the TJ, ran them in the comp to get a lower class.
also just installed a Poison Spyder fold down tire carrier i got from my BIL free off his his jeep. something about it wasn't great for a family rig :lol: should be awesome on the YJ.

1) Towing/camping with the enclosed is freakin awesome.
2) ProEagle jacks are WORTH the money!
had it out a few times and things are working really really well. a few issues though.
Steering:
currently just the power box with reduced leverage since i wanted the option for more deg or steering later. it's like driving manual steering in the rocks, it sux, it has to all go. time for full hydro ... eventually.
fuel system:
PSI drain back was super bad and it wouldn't start to save it's life, also was running only 44psi when it needs 52+ and was way off it's game. solved all this by FINALLY going to a fuel cell in the back to replace the factory tank, returnless fuel rail, and fender mounted adjustable PSI reg. soooo much more room in the back now, and super glad i went with the holy in-tank cuz it's quite and was easy.

more stuff to fix!
BDS 2" full military wrap leaves, and i'd never use anything but. i didn't even know it was broken til i was home and washing the jeep! these leaves lasted me 17+ years of abuse, so they owe me nothing ... BDS has a lifetime warranty, but i lost the proof of purchase a decade ago. ordered 4 new ones, but i'm worried it's going to be like 3" taller than now :james:

I had BDS on my TJ. Can’t beat the warranty.
well ... poop ... replaced 2" BDS springs with 2" BDS spring and got a 3.25" lift :james:
picture below is just the front leaves swapped, and it's almost level with the rollers n 40s! i ended up taking out the 4th leaf and she squatted another 1.5", so i'm good with leaving it at a 1.75" lift for now. should settle down another 1"+ after the first run or 2 hopefully.

shoot! i didn't get a picture of after ...
so the rear leaves went in same as the front missing the 4th leaf, everything seams good. it rides SO much better on the street it crazy. and it still fits into the enclosed so we're good!
